Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723864, here are decompositions:

13 + 8723851 = 8723864
31 + 8723833 = 8723864
43 + 8723821 = 8723864
157 + 8723707 = 8723864
211 + 8723653 = 8723864
271 + 8723593 = 8723864
313 + 8723551 = 8723864
367 + 8723497 = 8723864

Showing the first eight; more decompositions exist.
